Hi there,
I am trying to develop a simple application that must write information within a micro SD card (nothing too fancy, it is just plain data read from the internal accelerometer sensor).
/*********************************/
First of all, let me summarize what I am using and what program I have uploaded to the device:
- Hardware:
- Xiao BLE Sense.
- Round display expansion board.
- A 16GB micro SD card.
- Software:
- Visual Studio Code.
- nRF Connect for VS Code Extension Pack (latest version).
- nRF Connect SDK Toolchain v2.5.2
- nRF Connect SDK v2.5.2
- Zephyr OS.
I have downloaded the FatFS example from the zephyr GitHub (including some additional new prints only), which compiles and loads to the devices without any issue... but the outcome I receive is not good at all:
It may be something wrong in either the app.overlay or prj.conf files (or somewhere else, I do not know, I am new using the Zephyr OS).
In any case, I attach those two so as you may take a look at them:&spi2 {
compatible = "nordic,nrf-spim";
status = "okay";
cs-gpios = <&gpio0 0x1C (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
pinctrl-0 = <&spi2_default>;
pinctrl-1 = <&spi2_sleep>;
pinctrl-names = "default", "sleep";
sdhc0: sdhc@0 {
compatible = "zephyr,sdhc-spi-slot";
reg = <0>;
status = "okay";
mmc {
compatible = "zephyr,sdmmc-disk";
status = "okay";
};
spi-max-frequency = <24000000>;//8000000 /24000000 //16000000
};
};
&spi2_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 13)>,
<NRF_PSEL(SPIM_MOSI, 1, 15)>,
<NRF_PSEL(SPIM_MISO, 1, 14)>;
bias-pull-up;
};
};
&spi2_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 13)>,
<NRF_PSEL(SPIM_MOSI, 1, 15)>,
<NRF_PSEL(SPIM_MISO, 1, 14)>;
bias-pull-up;
low-power-enable;

/*********************************/
Additionally, for your information, I was able to write within the micro SD card by using the Arduino libraries and its examples, so I do not know whether I have something wrong configured in the Zephyr project, in the Visual Studio Code...
/*********************************/
Furthermore, I have seen that the Round Display has this caution message in the documentation:
Could it be something related to this?
/*********************************/
Thanks beforehand, sorry for the inconveniences and looking forward to hearing from you.
Kind regards.
Daniel.
